DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The motor vehicle door seen schematically and fragmentarily in FIG. 1 includes a door structure 10 and a door module 11 including a module plate 12 and an inside door handle assembly 14.

Door structure 10 includes a frame portion 16 defining a window opening 18 and an inner panel 20 defining a module opening 20 a and a plurality of apertures 22 in spaced surrounding relation to the opening 20 a. Door structure 10 is typically formed as a metal fabrication.

Module plate 12 is typically formed of a plastics material in a molding operation, has a size and shape generally conforming to the size and shape of the door inner panel opening 20 a, and is secured to the door inner panel within the dash lines seen in FIG. 1 and utilizing suitable fasteners passing through apertures 24 in the module plate and inner door panel apertures 22.

Inside door handle assembly 14 (FIGS. 2-6) includes a bracket 24, an inside handle 26, and a lock button 28 all preferably formed of a suitable plastics material.

Bracket 24 includes a main body portion 24 a, an arm portion 24 b, an arm portion 24 c and a trunnion structure 24 d.

Main body portion 24 a includes an arcuate flange portion 24 e and a floor portion 24 f defining an aperture 24 g.

Arm portion 24 b extends radially outwardly from flange 24 e in general alignment with aperture 24 g and includes a base portion 24 h reinforced by gussets 24 i. A keyway 24 j is formed in base portion 24 h. Keyway 24 i (FIG. 9) includes a relatively wide generally rectangular entry portion 24 j, a relatively narrow home portion 24 k and a funneled throat portion 241 interconnecting the portions 24 j and 24 k.

Arm portion 24 c extends generally at right angles to a line passing through aperture 24 g and keyway 24 i and defines a keyway 24 m. Keyway 24 m includes a relatively wide generally rectangular entry portion 24 n and a pair of cantilevered resilient fingers 24 p defining a relatively narrow home portion 24 q and having free ends 24 r terminating at and defining a throat between the wide entry portion 24 n and the narrow home portion 24 q.

Trunnion structure 20 d defines aligned trunnions 24 s, 24 t, 24 u and a cylindrical journal 24 v.

Handle 26 includes a main body portion 26 a and an actuator arm portion 26 b.

Main body portion 26 a defines a generally rectangular handle opening 26 b, a circular lock button opening 26 c, and aligned pivot pin openings 26 d.

Actuator arm 24 b extends generally radially downwardly with respect to the associated pivot opening 26 d and terminates in a linkage opening 26 e.

Lock button 28 includes a generally circular main body portion 28 a sized to fit within lock button opening 26 c of the handle and defining aligned pivot pin openings 28 b, and an actuator arm 28 c extending downwardly from the main body portion and terminating in a linkage opening 28 d.

In the assembled relation of the inside door handle assembly 14, the door handle 26 and the lock button 28 are pivotally mounted on the bracket 24 by a pivot pin 30 passing through an aperture 26 b, through journal 24 v, through trunnion 24 u, through trunnion 24 t, through trunnion 24 s, and through the other aperture 26 b. The handle and the lock button are thus pivotally mounted on the pivot axis defined by the pivot pin 30 for pivotal movement relative to each other and relative to the bracket. A coil spring 32 positioned around journal 24 v provides resilient resistance to the pivotal movement of the handle relative to the bracket.

The handle assembly is mounted on module plate 12 utilizing the keyways 24 i, 24 m in coaction with tabs molded integrally with the module plate. Specifically, a first tab 34 is formed integral with the module plate for coaction with keyway 24 i and a second tab 36 is formed integral with the module plate for coaction with keyway 24 m.

Tab 34 is formed on a module plate pad 12 a and has a “T” cross-sectional configuration including a relatively narrow stem portion 34 a upstanding from the pad 12 a and a relatively wide horizontal, generally rectangular bar portion 34 b on the free upper end of the stem portion.

Tab 36 upstands from a pad 12 b of the module plate and has a “T” cross-sectional configuration including a relatively narrow stem portion 36 a upstanding from the pad and a relatively wide, horizontal, generally rectangular bar portion 36 b on the free upper end of the stem portion. The module pads and the tabs are configured such that the tops of the pads 12 a and 12 b are at the same height and the tops of the bar portions 34 b and 36 b are at the same height.

Module plate 12 further includes an aperture 12 c defined in a module plate pad 12 d. Aperture 12 c and tabs 34 and 36 have a geometrical inter-relationship generally corresponding to the geometrical inter-relationship between aperture 24 g and keyways 24 i and 24 m.

In use, the door module is typically produced by a supplier organization and thereafter is shipped to an OEM manufacturer where the door module is assembled onto the door structure during the vehicle assembly procedure. According to the method and apparatus of the invention, the module plate and inside door handle assembly are produced by the supplier organization, the inside door handle assembly is mounted on the module plate in a manner to retain the bracket on the module plate while allowing limited adjustment of the door handle assembly relative to the module plate, the module plate and the door handle assembly are shipped to the OEM, the module plate is positioned on the door structure and fixedly secured to the door inner panel, the limited adjustability of the door handle assembly relative to the module plate is utilized to adjust the door handle assembly relative to the module plate to facilitate the installation of other motor vehicle door accessory items, and the door handle assembly is fixedly secured to the door structure.

Specifically, at the supplier location, the keyways 24 i and 24 m of a door handle assembly are positioned proximate the tabs 34 and 36 of a module plate; the bar portions 34 b, 36 b of the tabs are passed through the entry portions 24 j, 24 n of the keyways to position the base member 24 h of arm 24 b against the top of pad 12 a and position the arm 24 c against the top of pad 12 b; and the door handle assembly is slid linearly relative to the module plate to pass the tab stem portions 34 a, 36 a into the keyway home portions 24 k, 24 q. As the stem portion 36 a passes from the keyway entry portion 24 n into the keyway home portion 24 q, the fingers 24 p yield resiliently to allow the stem portion to move into the home portion as defined by the fingers whereafter the fingers snap back following movement of the tab stem portion into the keyway home portion to latchingly engage the tab stem portion and preclude inadvertent withdrawal of the tab from the keyway home portion. The height of stem portions 34 a, 36 a is slightly greater than the thickness of floor 24 j and arm 24 c so that the bar portions 34 b, 36 b closely and snugly overlie the floor 24 j and arm 24 c with the stem portions in the home position.

The tabs, keyways and fingers are dimensioned such that, with the stem portions positioned in the keyway home portions, a limited amount of linear adjustment movement of the inside door handle assembly relative to the module plate is permitted. Specifically, as best seen in FIGS. 9 and 11, the keyway home portion defined by the fingers 24 p is somewhat longer than the length of the tab stem portion 36 a so that the inside door handle assembly is free to move linearly relative to the module plate a limited amount without detaching the door handle assembly from the module plate. Following the mounting of the door handle assembly on the module plate, a door latch cable 40 is secured to actuator arm 26 b and a door lock cable 42 is secured to actuator arm 28 c. The mounting of the cables on the module plate is facilitated by lugs 12 e formed integrally with the module plate coacting with cable end connector members 44.

After the module plate has been installed on the inner panel 22 of the door structure the limited amount of adjusting movement of the inside door handle assembly relative to the module plate may be utilized to facilitate the installation of related door accessory items on the door structure. For example, the limited amount of adjusting movement may be utilized to facilitate the precise positioning of the cables 40 and 42 and this limited amount of adjusting movement also facilitates the installation of the interior trim panel (not shown) on the door structure. With respect to the door trim panel, manufacturing tolerance build-ups make it convenient to be able to move the inside door handle assembly in a limited manner relative to the door module to install the door trim panel on the door in surrounding relationship to the inside door handle assembly.

After the limited amount of linear adjusting movement of the inside door handle assembly relative to the module plate has been utilized to facilitate the installation of the various door accessory items, and with reference to FIG. 10, a screw 50 is passed downwardly through aligned apertures 24 g, 12 c and 22′ for engagement with a weld nut 52 positioned in surrounding relation to aperture 22′ whereby to complete the securement of the door module assembly to the door inner panel. Screw 50 preferably has a smooth shank with a dog tip lead 50 a so that it may search for and locate the threaded opening of the weld nut 52 irrespective of the final position of lateral adjustment of the inside door handle assembly relative to the module plate. In this regard, the apertures 24 g, 12 c and 22′ are all oversized with respect to the shank 50 b of the screw 50 to accommodate this lateral adjustment.

The method and apparatus of the invention will be seen to provide many important advantages. Specifically, the invention design allows for positive retention of the door handle assembly on the module plate during shipping between the supplier facility and the OEM facility; allows controlled adjustment of the door handle assembly relative to the module plate during vehicle assembly to facilitate the installation of door accessory items irrespective of tolerance build ups; reduces the number of fasteners (and potential water entry paths) for the door module assembly; allows the handle assembly to be used in multiple door applications including full window door frame door constructions and door constructions without a window frame; and provides a strong, positive mounting of the door handle assembly on the door structure by virtue of the triangulated mounting provided by the final fastener 50 and the spaced tabs 34 and 36. Further, the snap mounting of the door handle assembly provides universal mounting capability for the handle assembly and specifically allows the door handle assembly to be used in a door module application or in a conventional application where the door handle assembly is mounted directly to the door structure.
